Description René Fritz 2011-11-11 17:19:09 UTC 
Version:           2.3.0 (using KDE 4.7.3) 
OS:                Linux

I would like to see a function to reduce the last image editing function for a certain amount. Gimp has a similar function.

Example: Old photos are scanned and have ugly colors. Let's say normalizing (or one of the other automatic enhancment functions) gives good results to enhance the fotos but the effect is far too much. In Gimp you can fade out the last operation which gives you a percent slider. Choosing 60% merges the orginal image with the modified by a 40/60 ratio.

This option could be provided in the batch editor by a pseudo filter which has exactly the same functionality and has to be placed after the function that should be applied by x percent.

Reproducible: Always



Expected Results:  
provide "fade out" function in image and batch editor

OS: Linux (x86_64) release 3.0.0-13-generic
Compiler: gcc

This can be implemented in AutoColors tool to set color adjustments effect.

I would be happy if it will be implemented in AutoColors.

I thought that could be a generic function that's why I described it that way that every 'effect' could be reduced afterwards.
